In this guide, we explore how to control IoT devices, manage them, the methods to command these smart entities over the Internet and remotely monitor them.

The Internet of Things (IoT) has quite literally changed the way the Internet influences our day-to-day lives, revolutionizing how we interact with our surroundings. From smart thermostats to intelligent home security systems, the ability to control IoT devices provides unprecedented convenience and customization. In this guide, we dive into the nitty-gritties of managing and controlling IoT devices, exploring the methods to command these smart entities over the Internet and remotely monitor them.

How to Control IoT Devices over the Internet

The primary method to control IoT devices is leveraging the Internet. Most IoT devices come equipped with communication modules, enabling them to connect to the Internet and be controlled remotely. Here's how you can initiate control over the internet:


Ensure that both the IoT device and the device you are using to control it are connected to the Internet. This can be through Wi-Fi, cellular networks, or other connectivity options.

Platform Integration:

Many IoT devices are integrated into cloud platforms or specific applications. To control them over the Internet, you typically need to register the device on the relevant platform and use the associated application.

User Authentication:

Security is paramount when controlling IoT devices over the Internet. Ensure that the control interface requires user authentication to prevent unauthorized access.

How do I Control a Device in IoT?

IoT device control often involves the use of dedicated applications or platforms provided by the device manufacturer. These applications serve as a bridge between the user and the IoT device, offering a user-friendly interface for managing settings and functions. Here's how you can use IoT device control applications:

Step 1: Download and Install

Find and download the official application for your IoT device from the respective app store. Install the application onto your tablet or smartphone.

Step 2: Device Pairing

Follow the pairing or setup process specified by the application. This typically involves connecting the IoT device to your home network and registering it within the application.

Step 3: Remote Control

Once the device is paired, you can control it remotely using the application. This may include adjusting settings, monitoring status, or triggering specific actions.

How are IoT Devices Controlled?

Voice-controlled virtual assistants have become increasingly popular for managing IoT devices. Leading platforms like Amazon Alexa, Google Assistant, and Apple's Siri allow users to control a variety of IoT devices using natural language commands. Here's how to set up voice control:

Step 1: Integration

Ensure that your IoT devices are compatible with the chosen virtual assistant platform. Most major IoT manufacturers provide integration with popular virtual assistants.

Step 2: Device Discovery

Use the virtual assistant's app to discover and connect with your IoT devices. This typically involves linking your IoT device account with the virtual assistant.

Step 3: Voice Commands

Once connected, you can control IoT devices using voice commands. For instance, you can say, "Hey Alexa, turn off the lights" to control smart lighting.

How to Control IoT Devices Remotely?

The essence of IoT lies in its ability to be controlled remotely. This is particularly useful when you are away from home or want to monitor and adjust devices from a different location. Here's how you can remotely monitor and control IoT devices:

Cloud Connectivity

Many IoT devices use cloud services for remote connectivity. Ensure that your IoT device is registered on a cloud platform that allows remote access.

Mobile Applications

Use mobile applications associated with your IoT devices. These applications often provide real-time updates and control options, allowing you to remotely monitor and adjust settings.

Security Considerations

Be mindful of security measures when accessing IoT devices remotely. Use secure connections, enable two-factor authentication, and regularly update passwords to protect against unauthorized access.

Challenges and Considerations

1. Security Concerns:

Security remains a critical consideration when controlling IoT devices, especially over the internet. Here’s what you can do to mitigate security risks:

  • Secure Connections: Always use secure and encrypted connections, especially when accessing IoT devices remotely. Avoid using default or weak passwords.
  • Firmware Updates: Keep the firmware of your IoT devices up to date. Manufacturers often release updates that help address and mitigate security vulnerabilities.
  • Network Segmentation: Consider segmenting your home network to isolate IoT devices from critical devices like computers and smartphones. This helps contain potential security breaches.

2. Interoperability Challenges:

The diverse landscape of IoT devices sometimes leads to interoperability challenges. To address these challenges, you must pay attention to:

  • Platform Compatibility: Choose IoT devices that are compatible with popular platforms and virtual assistants to ensure seamless integration.
  • Standardized Protocols: Manufacturers should adhere to standardized communication protocols to enhance interoperability. Protocols like MQTT and CoAP are widely used in the IoT ecosystem.
  • Integrated Ecosystems: Opt for devices within the same ecosystem or from manufacturers that collaborate to ensure better compatibility and integration.

3. Power Consumption and Efficiency:

Remote control and monitoring can impact the power consumption of IoT devices. Here’s what you can do to enhance efficiency:

  • Power Management: Configure IoT devices to optimize power consumption. Disable unnecessary features or set devices to low-power modes when not in use.
  • Energy-efficient Devices: Choose energy-efficient IoT devices and sensors to minimize the impact on the environment and reduce the frequency of battery replacements.
  • Scheduled Controls: Implement scheduled controls to automate device actions based on specific time intervals, reducing the need for continuous remote monitoring.


Controlling IoT devices opens up a world of possibilities, providing convenience, efficiency, and customization in our daily lives. Whether it's adjusting the thermostat before arriving home, turning off lights using voice commands, or monitoring security cameras remotely, the control of IoT devices enriches our interactions with the digital world.

As we navigate the advantages and disadvantages of IoT, it's essential to prioritize security, consider interoperability, and embrace energy-efficient practices. The evolving ecosystem of IoT promises even more sophisticated control options, integration with emerging technologies, and a seamless amalgamation of the physical and digital realms. Mastering the art of controlling IoT devices not only enhances our connected experiences but also lays the foundation for a smarter and more responsive future.


1. What software is used to control IoT devices?

Controlling IoT devices often involves using dedicated software or applications provided by device manufacturers. These applications act as interfaces, allowing users to manage and control their IoT devices. Additionally, voice-controlled virtual assistants like Amazon Alexa or Google Assistant can also serve as a means to control IoT devices through voice commands.

2. What is the use of controlling devices remotely using IoT?

Remote control of devices using IoT offers unparalleled convenience and flexibility. It allows users to monitor, manage, and adjust IoT devices from any location with an Internet connection. This capability enhances efficiency, enables automation, and provides a seamless way to customize and optimize the functioning of connected devices, contributing to a more convenient and connected lifestyle.

3. Who controls the IoT?

The control of the IoT ecosystem is decentralized and distributed among various stakeholders. Users control their individual IoT devices through applications, platforms, or voice assistants. Device manufacturers and service providers may offer centralized control platforms. The overall governance and standardization of IoT protocols involve collaboration among industry organizations, technology developers, and regulatory bodies to ensure interoperability, security, and ethical considerations.
